Title: Cylinder for magnetic recording and reproduction
Inventor: MIZOBUCHI YASUO
IPC: G11B15/61
Filed: 1990-05-28
Abstract: PURPOSE:To suppress deformation of a stator cylinder at fixing and to make recording and reproduction stable by providing a slit notch to a cylinder side face around a stator of a cylinder stator member, decreasing the thickness of the cylinder side face more than other part of the cylinder and decreasing the stiffness of the stator. CONSTITUTION:A slit 3 and a mount screw hole 4 are provided to a stator 2 and a stator cylinder 1 is fixed with a cylinder stator member 5 by a mount screw 6. The deformation of the stator cylinder 1 due to a minute shape of each stator face of the stator cylinder 1 and the cylinder stator member 5 is less because the stator 2 with low stiffness receives the effect largely. Thus, the deformation of the stator cylinder is small and the magnetic tape wound on the cylinder is guided normally, then the recording and reproduction of a magnetic tape are made stable.

Title: Device and method for data management
Inventor: TAKAHASHI SHIYOUICHI
IPC: G06F12/00
Filed: 1993-05-13
Abstract: PURPOSE:To prevent design drawing data, specially, existent drawing data and updated design drawing data from being destroyed at the same time by providing a storage means which stores only the updated design drawing data. CONSTITUTION:Each time drawing data are moved, the updated design drawing data are stored in an updated data storage means 5a for a set time. At intervals of, for example, one hour, the data are stored in the updated data storage means 5a for this set time and then transferred to an updated data batch storage means 5b each time one hour is elapsed. Then updated design drawing data of plural generations of several hours are transferred to a design drawing data storage means 4A at a time to update design drawing data. Namely, the updated design drawing data generated during designing operation are stored not in a drawing data storage means 4A, but in the updated drawing data storage means 5a for the set time of another file. Therefore, even if the updated design darwing data are damaged during the designing operation, the updated design drawing data of up to one hour are only made ineffective.

IPC: H01J49/40
Filed: 1986-06-11
Abstract: PURPOSE:To enable high resolution and high ionic arrival efficiency to be realized, by installing an ion reflector to concurrently perform energy focusing of flying ions and spacial focusing of ionic orbits. CONSTITUTION:When intensity of electric field in an ion reflector part is set to monotonously decrease as it becoming distant from an ion-generation point S0 in the z direction, its potential component phi becomes an inversesquare type on an arbitrary flat plane (r-z flat plane) containing a z axis. In such a potential distribution, an equipotential plane becomes in a recessed shape in which it is orientated to the ion-generation point S0 with the z axis centered. Ions incident from the side of the ion-generation point So can be hence focused toward the z axis and reflected. Appropriate disposal of the ion-generation point S0 and the ion-focusing point S3 enables a time-of-flight mass spectrometer capable of concurrent energy and directional focusing to be manufactured.

Title: Electrochemiluminescence detecting cell
Inventor: MIYAHARA YUJI
IPC: G01N33/543
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain an electrochemiluminescence detecting cell whose reproducibility is high and which obtains a high S/N ratio by a method wherein a recessed part is formed on a working electrode and magnetic beads are captured by the recessed part in a one-to-one manner so as to emit light. SOLUTION: A plurality of recessed parts 9 are formed on a conductive electrode plate 8. The size of every recessed part 9 is matched to the size of every magnetic bead 6. The bottom face 10 and side faces by every recessed part 9 act as electrodes. It is required to completely remove every bead 6 which is captured once when a next measurement is performed. When the area of the bottom face 10 is made smaller than that of an opening part in such a way that a cross-sectional shape is an inverted trapezoid, every bead is removed efficiently. It is required to deliver electrons with reference to every working electrode so that a luminescent reagent can emit light. As a result, only the luminescent reagent which is close of every working electrode out of luminescent reagents which are fixed to every bead 6 participates in luminescence.  In every working electrode, at least four places on side faces of every recessed part 9 are obtained as points coming into contact with every bead 6, every bead 6 can come into contact with the bottom face 10 when the structure of every recessed part is made optimum, and every bead 6 owns five contact points in common. Since electrochemiluminescence is generated in every contact point, it can be measured in a high S/N ratio.

Title: Pipe coupling
Inventor: HAMA TOMIO
IPC: F16L37/091
Filed: 1995-06-02
Abstract: PURPOSE: To prevent the breakage of a lock claw by an external force, by forming the lock claw to have inner and outer rings divided plurally, in a pipe coupling furnishing a lock claw to block the movement in the pull-out direction of a pipe inserted in the coupling main body, by encroaching its inner end edge to the outer wall of the pipe. CONSTITUTION: When a pipe 38 is inserted in a coupling main body 11 from the direction of an opened cylindrical body 26, the pipe 38 moves while expanding the inner side ring 119 of a lock claw 112 against the elastic force of connections 120. Since the outer peripheral edge of the pipe 38 is bent in the inserting direction side of the pipe 38, the movement of the lock claw 112 together with the pipe 38 is blocked, and the lock claw 112 is abutted obliquely to the outer wall of the pipe 38 thereafter. When the pipe 38 is tried to pull out under such a condition, the inner rings 119 encroach to the pipe 38, so as to prevent the removal of the pipe 38. Furthermore, the lock claw 112 is made to avoid the stress concentration to the connections 120, by forming the outer cutting parts 113 in a U-shape.
